A FFllQE FURNACE-TILE.

To all whom it may concern:

Be it known that I, EDVARD, C. MEIER, a citizen of the United States, residing at Phoenixville, in the .county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Furnace-Tile, of which the following is a specification.

My invention relates to improvements in furnace tile, the object of the invention being to provide a furnace tile which may be manipulated between the tubes of the boiler, so that the tile may be moved upwardly among the boiler tubes and supported upon any set of tubes so as to position the baffle anywhere desired. In many cases, particularly where quick combustible fuel is used, it is desirable to locate the lowest baflie at a point above one, two, or three rows of boiler tubes, so that these lower boiler tubes will receive the direct heat from'the fire box, and it is impossible with tiles such as ordinarily employed to so locate a bafiie which will withstand the intense heat to which it is subjected.

Boilers have been equipped with metal baffles located at various points in the boiler tubes, but such metal baffles would not stand the extreme heat to which a baflie such as above referred to is subjected, and it is the purpose of my invention to provide a tile which will withstand any heat to which it might be subjected, and which can be manipulated among the lower tubes of the boiler and rested upon any set of tubes desired.

WVith these and other objects in view,the invention consists in certain novel features of construction and combinations and ar rangements of parts as will be .more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in longitudinal section illustrating my improved tile in position in a boiler. Fig. 2 is a perspective view of one of my improved tile. Fig. 3 is a fragmentary view in cross section showing the position of the tile on the water tubes. Fig. dis a fragmentary view illustrating the manner of moving the tile between the tubes of the boiler in order to position the tile where desired, and Fig. is a fragmentary view illustrating a modified form of tile.

connected by a staggered arrangement of water tubes said water tubes located above an ordinary fire b'oX l having abridge wall 5 over which the smoke and gases pass to the boiler tubes.

6 and 7 represent bafiies which are formed by my improved tile 8. The battle 6 is supported on the upper row of boiler tubes 8 with the opening at the forward end of the boiler, and the battle 7 is supported on the third row of boiler tubes counting from the bottom, with the opening at the end of the baffle adjacent the rear end of the boiler, so that the smoke and gases from the fire box pass rearwardly in direct contact with the lower boiler tubes, thence forwardly in contact with the other boiler tubes, and then out through the stack 21.

While it'is common in boilers to locate two, three, or more baflies in various positions, it is impossible with ordinary forms of tile to position the bafiles on an intermediate row of boiler tubes. because the tile cannot be movedbetween the tubes. Especially is this true when it is understood that the only practical way to position the tile on the tubes is from the bottom of the boiler, and it is the purpose of my invention to provide a tile of a shape which can be so manipulated between the tubes of the boiler that the baflles may be located upon any desired row of tubes, and the tile forming the baffles can be placed in position, removed when worn, and renewed with little difficulty.

As above stated, under certain existing conditions, it has been found that best results are had by subjecting two, three, or more of the lowest'rows of boiler tubes to the direct heat of the fire, and hence my improved tile has a special advantage as it enables the baffle to be readily located where the best results may be had.

Each tile 8 is formed on its lower face with two straight converging surfaces 10 and 11, meeting at the longitudinal center of the tile and forming an angle 12. The sides of the tile are curved in the arc of a circle as shown at 13, and this are is slightly different from the arc of the circle of the boiler tubes, so that when the tile rests upon the boiler tubes, there is a slight space between the lower portions of the curved sides 13 and the boiler tubes as shown clearly at 14 in Fig. 3. This is desirable because of the fact that tiles are more or less imperfectly made, and furthermore because of the fact that the tubes expand and contract, and any expansion of the tube cannot bind the tile, but will tend to elevate the tile slightly.

The upper face of the tile at its ends is curved convexly as shown at 15, and the intermediate portion of the upper surface of the tile is curved concavedly forming a trough 17 which extends throughout the length of the tile, and hence all of the baffles are provided between the boiler tubes with troughs in which the soot collects and can be blown out whenever desired.

Attention is called particularly to Fig. 4 which illustrates in dotted lines the manner of manipulating a tile in its passage upwardly between the boiler tubes. It will be noted in this view that the fiat bottom surfaces 10 and 11 engage alternately as the tile is fulcrumed on the angle 12, so that while one fiat surface engages in the initial movement, the tile is turned or twisted so that the other fiat surface engages on a continued movement, and by swinging the tile back and forth with the angle 12 as the fulcrum, the tile can be readily moved between the tubes and finally find lodgment on the boiler tubes desired.

In Fig; 5, I illustrate a modified form of tile 18 which is adapted for use where the boiler tubes 3 are closer together than in the preferred form. This tile is of the same general contour as the preferred form, except that the flat surfaces 19 and 20, corresponding to the flat surfaces 10 and 11 are longer than said last-mentioned surfaces, and the general shape of the tile is flatter or narrower in accordance with the necessity due to the close proximity of the boiler tube.

By reason of the shape of the tile, its angle 12 not only enables the same to be easily ground down to insure its passage be tween the tubes, but it insures a low center of gravity to permit a ready manipulation to position the tile.

Various other slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to seizure by Let ters Patent is:

1. The combination with a plurality of rows of staggered boiler tubes, of baflles supported on the boiler tubes composed of a plurality of tile, each tile formed on its lower face with two straight converging surfaces meeting at the longitudinal center of the tile and forming an angle, the sides of each tile curved in the are of a circle throughout the length of the tile and resting throughout their length on the boiler tubes, substantially as described.
